I mean, if I wanted to knit pick - I guess theoretically the earth isn’t a perfect ball, and the mountains aren’t flat, so you would need a globe with topography for it to really not be a projection but a model

The topography is basically not significant.
The elevation of the highest point on Mt. Everest is 8,848 meters. Compared to the radius of the Earth itself (averaging 6,371,000 meters and varying about 10,000 meters from that average), that 0.139% difference in radius at that mountain not going to be noticeable.
If you shrunk the entire earth down to the size of a 2 meter diameter ball (1 meter radius), Mt. Everest would rise about 1.39 millimeters from the surface.
Simple imperfections in polishing a representative globe would represent larger variations in altitude than exist on the Earth itself.
